void is a special type indicating the absence of any value. There are no objects of void; instead, void is used for deriving more complex types.
Void Functions
Use the void keyword as a function return type if the function does not return a value. For example:
void print_temp(char temp) { Lcd_Out_Cp("Temperature:"); Lcd_Out_Cp(temp);
Lcd_Chr_Cp(223); // degree character
Lcd_Chr_Cp('C');
}
Use void as a function heading if the function does not take any parameters. Alternatively, you can just write empty parentheses:
main(void) { // same as main()
...
}
Generic Pointers
Pointers can be declared as void, meaning that they can point to any type. These pointers are sometimes called generic.
